摘要： A storage system has a host system and a storage apparatus. The storage apparatus includes a first volume and a second volume to store files transmitted from the host system. The host system has: a display unit for displaying the content of a first directory in the first volume and the content of a corresponding second directory in the second volume; and a switching unit for switching, on the display unit, between the display showing the content of the first directory and the display showing the content of the second directory. The storage apparatus further has: a searching unit for searching for the second directory based on a table having a migration path from a root directory to the first directory in the first volume stored therein; and a transmitting unit for transmitting the content of the second directory, which is searched for by the searching unit, to the host system.

摘要： A disk array system is provided, which can improve data reliability by verifying addressing correctness of data access by applying a redundant code to user data even if using an HDD compatible with serial ATA, etc. whose sector length cannot be extended. When writing the object data to an HDD, a controller stores partly-extracted data of the object data in a control area and performs an XOR operation between the partly-extracted data and a check code generated by calculations. Then, the operation-resultant data (CC-embedded data) are returned to the object data and written in the HDD. Also, when reading the object data from the HDD, the controller fetches the CC-embedded data, performs an. XOR operation between the fetched data and the check code, and compares and collates the operation-resultant data with the partly-extracted data in the control area to check the addressing correctness and restore the user data.

摘要： A disk array apparatus using an SAS can transfer data without lowering a transfer efficiency of data even if rates of a plurality of physical links connected to a controller and storage device are different. A plurality of HDDs are connected to a controller through an expander. Data are transferred from the controller to the expander and then to HDD. In this connection, the controller and the expander transfers a set of transfer data in a plurality of the HDD-side physical links. The controller-side physical link integrates the transfer data, and multiplexes them to transfer. A plurality of HDDs-side physical links separates the transfer data to transfer in parallel.

摘要： The present invention enables to secure data reliability by avoiding data loss in an early failure period of an operation of a disk array system to which no particular measures have been taken conventionally. A controller of the disk array system stores first data to be stored in a HDD into a part of the region of one or more HDDs of an overall storage region composed of a plurality of HDDs and stores backup data of the stored first data into a part of the region of one or more HDDs in such a manner that they may be stored in the different HDDs. When there are no enough free space regions to store the first data in the overall storage region, the region in which the backup data is stored is overwritten to be used.
